It is not realistic for users to get clear enough line alignment with any manual line drawing tool under night vision illumination work fields, however, the appearance of infrared line laser alignment has just changed the situation greatly. When this infrared laser module is working together with those of infrared laser device, such as a CCD camera, black and white camera or infrared laser camera, this laser line generator is just producing highly accurate and highly straight infrared laser line, making sure of clear line positioning for special work fields including military targeting, laser medical treatment device, military targeting and surveillance system etc.
Users can make free selection of its laser lens degree, thus this infrared line laser alignment produce different laser beam fan angle and generate different size of IR laser line length in distance. Within its wide range output power of 5mW to 400mW, infrared laser module is workable at quite long work distance, and generate super long line length from 0.5 meter to 6 meters. This IR laser line measuring tool is just used as an accessory part, after very simple adjustment of laser line targeting direction and line thickness, it can finally obtain high accuracy line alignment perfectly.
